						This patch brings over a few features from MirBSD:
 | 
				
			||||||
 | 
						* -fhonour-copts
 | 
				
			||||||
 | 
						  If this option is not given, it's warned (depending
 | 
				
			||||||
 | 
						  on environment variables). This is to catch errors
 | 
				
			||||||
 | 
						  of misbuilt packages which override CFLAGS themselves.
 | 
				
			||||||
 | 
						* -Werror-maybe-reset
 | 
				
			||||||
 | 
						  Has the effect of -Wno-error if GCC_NO_WERROR is
 | 
				
			||||||
 | 
						  set and not '0', a no-operation otherwise. This is
 | 
				
			||||||
 | 
						  to be able to use -Werror in "make" but prevent
 | 
				
			||||||
 | 
						  GNU autoconf generated configure scripts from
 | 
				
			||||||
 | 
						  freaking out.
 | 
				
			||||||
 | 
						* Make -fno-strict-aliasing and -fno-delete-null-pointer-checks
 | 
				
			||||||
 | 
						  the default for -O2/-Os, because they trigger gcc bugs
 | 
				
			||||||
 | 
						  and can delete code with security implications.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
						This patch was authored by Thorsten Glaser <tg at mirbsd.de>
 | 
				
			||||||
 | 
						with copyright assignment to the FSF in effect.
